I personally feel... its yet another passionate startup give away to the giants! Why should it always happen like this that the big fishes should always eat up the younger ones!! Why cant the new fishes refuse offers and instead see their company through?!

I think it's good that a company like Facebook deems these other companies as worth $19B, but the fact that they feel the need to buy them shows Facebook's insecurities with having any kind of competition to their own services.

It's like the big companies don't believe in their own development teams enough to trust them to come up with something to rival these smaller apps and programs. Maybe instead of spending that money on whatsapp they should've thrown it into their own apps and messenger facilities to bring them up to spec, if that makes any sense.
